SPECIFICATION forming part of Letters Patent No. 582,078, dated May 4,1897.

Application filed J 1 118 20, l 896.

T0 aZZ whom it may concern:

Be it known that 1, CHARLES MoOARRIQK, of Tivoli, in the county ofDutchess and State of New York, have invented newand usefulImprovementsin Pencil-Sharpeners, of which the following is a full,clear, and exact d.e-

scription.

My invention relates to improvements in pencil-Sharpeners, and has forits object to combine with a sharpener proper a suitable guide or holderfor the lead of a pencil, so that a true point may be readily obtained.

The improved pencil-sharpener is particularly adapted for use inconnection with pencils comprising a suitable casing and a lead adjustably held therein.

The invention will be fully described hereinafter and the features ofnovelty pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a plan View of the blank from which thebody of the holder isformed. Fig. 2 is a front View of the said holder. Fig. 3 is a side Viewthereof. Fig. 4 is a perspective View of a collar adapted to be insertedin the holder and serving as a guide for the sharpener proper. Fig. 5 isa perspective view of the sharpener proper. Fig. 6 is a front elevationof the complete device. Fig. 7 is aside view thereof; and Figs. 8, 9,and 10 are sectional plans taken on the lines 8 8, 9 9, and 10 10,respectively, of Fig. 6.

The improved pencil-sharpener consists, mainly, of three parts, namely,the sharpener proper, the holder for the sharpener, which also forms aguide for the lead of the pencil, and a ring or collar secured to theholder and adapted to receive one end of the sharpener proper.

The holder is made of a strip of sheet metal, such as shown in Fig. 1,said strip having a rounded portion A at its center with an aperture A.The strip is adapted to be folded along the lines ca a, forming therebya central or head portion A At a predetermined dis tance from the saidcentral portion the strip is provided with apertures A for a purposestated hereinafter. A second bend is made in the strip at pointsindicated by the lines Serial No. 596,277. (No model.)

b l), forming between the lines a ct and b b the side portions A.Between the apertures A and the lines I) b the side portions A areprovided with oblong apertures A Exteriorly the lines I) I) and c c arebent toward each other, so that the two semicircular recesses A willform an approximately circular aperture, as shown in Fig. 10. The stripis then return-bent above and along the portions A and a further bend ismade adjacent to the side members A on the lines cl 61, forming returnportions A between the lines o c and (Z (Z. The ends of the strip areformed with notches or recesses A whose sides extend approximately at anangle of forty-five degrees to the longitudinal axis of the strip. Thetwo notches when brought together, as shown in Figs. 2 and 6, form asquare, the sides of which are approximately equal to the diameter ofthe lead. Between the bend made on the lines at d and the ends the stripis bent inward at e e, forming loose longitudinal members A andtransverse end members A forming a yielding lead holder. Thelongitudinal members A are slitted, forming on each a tongue A which isbent into the form of a handle, as shown in Fig. 2, said handleprojecting through the apertures A of the side members A The sharpenerproper consists of a body B, having a longitudinal conical bore 13 and av segmental recess B in which is set the sharpener-blade O. The saidblade, instead of ranging parallel to the axis of the sharpener, isarranged obliquely thereto, as will be seen best in Fig. 5. The upperend of the sharp ener is provided with a milled head B which has ascrew-threaded aperture 13 into which is adapted to fit a screw D, whichpasses into the central aperture A of the holder. A

washer E is interposed between the head B and the central portion A ofthe holder.

The lower or free end of the sharpener fits into a collar or sleeve F,which is provided with projections F, forming clips to hold the saidcollar or sleeve on the holder, the said projections being insertedthrough the holes A in the side members A of the holder.

The operation of my improved sharpener is as follows: The pencil isintroduced from the end of the holder opposite to that carrying thesharpener proper, so that the lead G will project into the bore 13' ofthe sharpener and will engage the notches A of the transverse endmembers A while the case H will be engaged by the curved walls of therecess A The lead is then pointed by turning the milled head B so thatthe blade 0 sharpens the pencil in the ordinary manner.

It will be observed that the lead is held firmly and in an invariableposition relatively to the sharpener. It will also be observed that theguide formed by the members A A", and A is located in advance of thatend of the sharpener into which the lead is adapted to enter-that is,the lead is engaged by the guide before it enters the sharpener. Thesharpener proper may be readily removed by removing the screw D and thewasher E, whereupon the sharpener may be slid longitudinally on theholder until it comes out of the sleeve F.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination of a holder having a pencil-guideat one end, a rotatable pencilsharpener at the other end of the holder,and a ring or collar secured to the holder and adapted to receive thatend of the sharpener which is nearest the pencil-guide, substantially asdescribed.

2. A pencilsharpener, comprising a holder formed of a strip bent intorectangular form, said holder having a pencil-opening at one end andprovided with inwardly-projecting and recessed members spaced from theend formed with the pencil-opening and forming a lead-holder,substantially as described.

3. A pencil-sharpener, comprising a holder formed of a strip bent intorectangular form, said holder having a pencil-opening at one end andprovided with inwardly-projecting members spaced from the end having thepencil-opening and having recessed ends forming a lead-holder, and asharpener mounted in the opposite end of the holder, substantially asdescribed.

4:. In a pencil-sharpener, the combination of a holderhavin g spaced andalined openings at one end, a ring secured in the holder, a sharpenerhaving its lower end fitting in the said ring and a screw passingthrough the holder into the body of the sharpener, substantially asdescribed.

5. In a pencil-sharpener, a holder formed of a centrally-apertured stripbent at each side of the aperture to form an end and two side members,the lower portions of the side members being bent inwardly toward eachother, then return-bent, then bent upwardly approximately parallel withthe side members and then bent inwardly, the inwardlybent portions beingprovided with opposite recesses forming openings, substantially asdescribed.
